WILLIAM A. HOUCK, OF READING, PENNSYLVANIA.

COP-MOUNTING.

Application filed February 4, 1915.

T 0 all whom it may concern.

Be it known that I, WILLIAM A. HoUCK, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in Cop-Mountings, ofwhich the following is a specification.

My invention consists in an improved cop mounting for knitting machinesor the like, and the principal object in view is to provide for socontrolling the unwinding thread as to effectively avoid any tangling orbreakage such as is ordinarily liable to occur. It is fully described inconnection with the accompanying drawings, and the novel features arespecifically pointed out in the claims.

Figure 1 is a sectional elevation of a device embodying my completeinvention in preferred form, the parts being illustrated in normalposition preliminary to placing a full cop thereon. A partially used copis indicated in dotted lines, together with the corresponding positionof the movable thread-supporting disk. Figs. 2, 3, and 4 are separatedetail views.

The partially used cop 2, which is indicated in dotted lines, representsan ordinary form wound upon an inner tube or quill 3; the latterordinarily fitting upon a spindle or support perpendicularly fixed to asuitable bracket or base plate 5.

My invention consists in the novel mounting therefor, as fullydescribed.

The quill 3, as shown, is of the usual conical form, and fits upon acorrespondingly shaped sleeve 10, fixed to the supporting spindle 11.This spindle is adjustably fixed to the base plate 5; its squared andscrewthreaded lower end portion 12 extending through a square aperturein the base plate as illustrated, and being provided with a regulatingnut 13 for lowering the spindle, while a spring 14 is arranged to pressit upward, thus enabling it to be conveniently and accurately adjustedperpendicularly.

A cylindrical cup 20 is provided on the base plate 5, concentric withthe cop sup porting spindle 11, and is formed with an outwardly flangedrim 21. Slidably mounted upon this cup is a dished thread-supportingdisk 22, which is normally raised against said rim flange by a lightcoiled spring 23.

When a full cop S is placed tightly upon its support 101l, the outeredge portion Specification of Letters Patent.

thereof is adapted to bear upon the threadsupporting disk 22, and topress the latter downward from its normal position shown in the drawing;the purpose being to provide a support for any sagging of the thread asit is unwound from the cop and to prevent the thread from getting underthe cop or tangling so as to interfere with proper operation. As the copis reduced in diameter by the unwinding of its thread, the disk 22 ispressed upward upon the cup 20 by the spring 23 as required, so as to atall times lightly contact as stated with the edge of the graduallyreducing cop.

The quills 3 of different cops, and the winding of the thread thereonrelative to the lower edge 3 thereof, ordinarily vary so as to call forperpendicular adjustment of the cop support as already described; theadjusting nut 13 being readily turned as may be required to so positionthe full cop that the disk 22 will be properly lowered at the start, andthus permit of its automatically following up as the cop is reduced indiameter by the unwinding.

It will be understood that the weight of the cop is at all timeswhollycarried by the support 10-11, and that the contact of thethread-supporting disk 22 with the outer bottom edge thereof is effectedmerely by the light spring 23; so that such contact will produce noobjectionable friction though adapted to satisfactorily serve thepurpose described.

The specific construction shown may obviously be modified withoutdeparting from the essentials of the invention as defined in the claims.

IVhat I claim is:

1. In combination with a supporting base, a thread supporting diskmounted thereon. a central cop support'comprising a spindle having ascrew-threaded end projecting through said base and a cop-engagingsleeve fixed to the spindle above said base, a spring seating betweensaid base and sleeve, and a nut to perpendicularly adjust said spindleupon said base.

2. In combination with a supporting base, a cop support fixed theretoarranged to rigidly carry the cop, and a spring-pressed disk of dishedform adapted to automatically maintain contact with the outer bottomedge of the cop.

3. In combination with a base plate. a cop support perpendicularlyadjustable thereon,

and a concentric spring-pressed thread-supplate and a spring-pressedthread-support- 10 porting disk carried thereby. my; disk 'slldable onsaid flanged cup.
